UN-LOADING APPARATUS.

SPECIFICATION formingpart of Letters Patent Np. 742,125, dated October 20, 1903.

Application filed September 24, 1901. .Serial No. 76,380. (No model!) To all whom it may concern: section is also made more firm and secure by Be it known that 1, CHARLES P. MARTIN, a rod 6, running through the side rails C and citizen of the United States, residing at Le-. secured by nut d. Attached to the top of mont Furnace, in the county of Fayette and side rails C in any suitable manner are State of Pennsylvania, have invented certain metal rails E, curved at f, as shown, so as to 55 new and useful Improvements in Unloading form abutments to engage with the front Apparatus; and I do hereby declare the folwheels of an ore-car run upon said rails and lowing to be a full, clear, and exact descripprevent the car from going forward when the tion of the invention, such as will enable track-section is tilted.

IO others skilled in the art to which it appear Attached to the rearof the track-section 6o tains to make and use the same. in any convenient manner is hook F, so ar-' My invention relates to an improvement in ranged as to engage with catch 9, attachedv unloading apparatus, and more particularly to the turn-table a. Said hook F when ento means for conveniently and automatically 'gaged with catch g prevents the track-secdumping ore-cars, the object of the invention from tilting before desired. 6 tion being to provide a simple and efficacious G is a rod of any desirable material run means by which a loaded car can be convenning through holes in the rear of the trackiently and automatically tilted for the pursection, as shown, and turned upward at pose of discharging its contents in any deeach end to form handles h. Attached to or sired direction and returned to its normal made a part of said rod G and sufficiently position. near the ends of thetrack-sect-ion on each My invention also has for its object the side to engage with the rear Wheels of anoreproviding of means whereby ore or coal cars car when run upon said track-section are two run from a plurality of mining-tunnels or blocks or abutments H, which when turned 25 coal banks can be taken from a common upward and toward the car, as shown in the point and dumped in any direction and redrawings, by handles h hold the car from returned to their respective tracks. ceding from its position on the dumping ap- The objects of my invention are attained paratus. When it is desirable to release the by the construction illustrated in the accomore-car from track-section C, the abutments 7 o panying drawings, of whichor blocks H are turned backward by means 80,

Figure 1 is a perspective of my device, of handles h, the lower end of the abutments showing it ready for operation and showing H resting against the ends of rod 1, running tracks diverging from a common point. Fig. through the track-section near the rear there- 2 is a side view of truck, showing car and of and projecting sufficiently to engage with 5 dumping apparatus in a tilted position. Figs. the lower ends of said abutments H, as shown 3 and 4: are detail views of parts. in the drawings.

In the drawings, A represents an ordinary Ore-car G, which isprovided with a swingcar-truck with a platform and a turn-table a ing end-board, is run upon the track-section pivoted thereon by means of a bolt run from any desired direction, said track-section 40 through the center thereof. The turn-table turning with turn-table a, the car-truck A 0 a is supported by a plurality of wheels B, set beingon a track sufficiently below the grade in said truck-platform, as shown. upon which the ore-car track runs to admit Attached to the turn-table in any suitable of the ore-cars passing upon said track-secmanner is an axletree 0, upon which a tracktion. The ore-cars are then carried toany 45 section tilts. Said track-section is preferdesired point by means of car-truck A and 5 ably made of wood or any light material dumped by disengaging hookF from catch 9 and is composed of side rails G and braces and the tilting of the track-section. By plac D, which braces rest upon the turn-table a, ing said track-section upon axletree b at a as shown in- Fig. 1, thus holding said trackpoint in the rear of the center of said track-,

59 section in a horizontal position. The tracksection so that a larger portion of the tracksection will lie in front of the axletree the same will tilt automatically when hook F is released from catch g, and the contents of a car resting upon said track-section can be dumped in any direction by means of turntable a and the releasing of said hook F from the catch g. lhe forward end of the tracksection when in a tilted position rests upon truck-platform I, as shown in Fig. 2.

L is a heavy plate or bow-spring, at its central portion secured at c to the rear part of the turn-table, with its downwardly and outwardly extending free ends located below the sides of the track-section at points between the rear ends thereof and the horizontal axis on which said section tilts vertically.

mm are loose or pivoted connections between the free ends of said spring and the sides C O of the tracksection.

The arrangement is such that the loaded carwill tilt against the tension of said spring, thereby elevating its free ends. IVhen the car is emptied, lhe power of the spring is suffieient to return the track'section and car to the normal horizontal position. Other forms of springs and springs differently applied and applied to different forms of cars and unloading apparatus may be used, and I do not wish to be limited to the preferred form described or to the springapplied to the particular unloading car or apparatus instanced.

In the claims I have used the term carrier to designate, broadly, the movable portion of my apparatus, including generically the track-section and car, as it is obvious that the car or orereceptacle could, if desired, be made integral with the said movable tracksection,'the whole being transported together to and from the loading and dumping points.

Having thus described my invention, I would refer to patent of the United States, No. 671,025, granted to me April 2, 1901, for the general features of the unloading. apparatus herein described and upon which the subjectmatter of this application is an improvement and addition. I also refer to patent in Great Britain, No. 4,036 of 1901, application for which was made by me on the 25th day of February, 1901.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In an unloading apparatus, the combination of a pivotally-mounted movable carrier heavier at the tilting end, and a spring for the purpose of returning said carrier to its normal horizontal position.

2. In an unloading apparatus, the combination of a pivotally-moun ted carrier heavier at the tilting end, a spring for the purpose of returning said carrier to its normal horizontal position, and a catch for holding the carrier in its normal position when returned.

3. In an unloading apparatus, the combination of a tilting carrier heavier at the tilting end, and a returning-spring mounted thereon for the purpose of restoring the carrier to its normal position.

4. In an unloading apparatus, the truck, the tilting traclcsection, the catch, the hook and the returning-spring.

5. In an unloading apparatus, the truck, the turn-table, the tilting track-section and returning-spring.

6. In an unloading apparatus, the combi nation with a car, of a truck, a turn-table mounted thereon, a tilting track-section on said table, abutments .on said track-section adapted to engage the wheels of said car, means for limiting the movement of the car on the track-section and a returning-spring to return said track-section to its normal horizontal position.

7. In an unloading apparatus, the combination with a car, of a truck, a turn-table mounted thereon, a tilting track-section on said table, abutments on said track-section adapted to engage the wheels of said car, means for limiting the movement of the car on the track-section, a returning-spring to return the track-section to its normal position, and a catchforsecnring the tilting track-section when returned to its normal position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES P. MARTIN.
